Erosion Boots

A little rain can cause extensive and costly erosion damage over time when you are flying at speeds of 200+ mph. This makes every leading edge of your aircraft highly susceptible to erosion, particularly the nose which commonly houses flight critical instrumentation. Our erosion boot is a thin, clear polyurethane film that acts as a protective barrier between your aircraft and the damaging elements. It’s been dubbed a boot because it is formed into a 3 dimensional shape that fits exactly over the complex contours of your aircraft leading edges. This ensures a perfect and streamlined fit every time, plus the ultra high-strength adhesive guarantees a secure installation for years and years of service! Benefits:
  • Protects your investment and saves you on costly down time and maintenance.
  • Optimized thickness is virtually invisible to radar yet provides years of service.
  • UV stabilized to eliminate yellowing over time.
  • Extremely simple and easy to install.
  • Nearly invisible after installation.

Leading Edge Tape

A clear adhesive 0.305mm (0.012″) thick polyurethane film is available in un-formed (straight) tape for erosion protection on any flat leading edge. Ideal for erosion protection on numerous aircraft leading edges including wing leading edges, horizontal tail, landing gear, etc. Also works great for many other applications including automotive erosion protection. Available in five different widths. 100 feet per roll. Benefits:
  • Clear adhesive 0.012″ thick polyurethane film. 100 feet per roll.
  • Protect your investment and save thousands on costly maintenance.
  • Optimized thickness is virtually invisible to radar and provides years of use.
  • UV stabilized to eliminate yellowing over time.
  • Extremely simple and easy to install.
  • Nearly invisible after installation.

Antenna Masking

A selection of boots specifically designed for protecting aircraft antennas. Prevent erosion and reduce costly repair and degradation to your aircraft's communication critical instruments! Benefits:
  • Protect your investment and save thousands on costly maintenance.
  • Optimized thickness is virtually invisible to radar and provides years of use.
  • UV stabilized to eliminate yellowing over time.
  • Extremely simple and easy to install.
  • Nearly invisible after installation.

Helicopter Radomes

A selection of radome erosion boots for helicopters. Protect helicopter radomes from erosion in normal flight as well as takeoff, landing, and low altitude hover where erosion from dust and other particulates suspended in the air becomes a greater concern. Benefits:
  • Protect your investment and save thousands on costly maintenance.
  • Optimized thickness is virtually invisible to radar and provides years of use.
  • UV stabilized to eliminate yellowing over time.
  • Extremely simple and easy to install.
  • Nearly invisible after installation.

FAQs

What is the shelf life?
PM Research, Inc. manufactures and distributes erosion protective masks and leading edge tape. These products are manufactured to our specifications and offered off the shelf for our customers’ use. Our high standards regarding quality and service have been the primary factor in making PM Research the leader in radome erosion protection. Although we have no control over our customers’ atmosphere or storage conditions, we recommend the following:
  • Keep product sealed in its original box.
  • Do not store anything else with or on the product.
  • Store the product in an atmosphere that is clean and dry.
  • Store the product at room temperature.
  • Continually rotate product stock.
If above conditions are met, shelf life is not an issue since it will be greater than five years.
What FAA form or approval is required to install erosion protective masks (boots)?
Since the installation of PM Research, Inc. masks is similar to applying a thick coat of paint, the PM Research, Inc. line of Erosion Protection Masks (boots) can be installed and the aircraft returned to service in the same manner as if it was just painted. Our products are not structural in nature and are not required to be FAA approved. We are not required to have a STC and we are not required to be PMA approved. Form 8130 is not required.
Is the product traceable?
The erosion mask products are produced by PM Research Inc. in Wellsville, NY and are fully traceable. Certificates of Conformance are available.
How is it installed?
The material is self-adhesive. The backing is peeled off and the product is installed wet; with a solution of distilled water, alcohol and dish washing liquid. This prevents the material from sticking until the location of perfect fit is located. The moisture is then pressed out with hands and also with a plastic squeegee. A trim line is established and the mask is trimmed with a sharp blade.
How soon can I fly after installation?
60 percent adhesion is obtained after 1 hour and near 100 percent after 24 hours. It is acceptable to fly 1 hour after installing a radome boot because the slip stream will hold it in position and not try to peel it off. For other products, with edges that are exposed to the force of the relative wind, a longer drying time is required.
Is maintenance required over the life of the boot?
Clean and wax periodically as required. We recommend that you use full strength Knight’s Spray Nine ® or full strength Ultra Mr. Clean ® to clean the mask (boot). Use a non-silicon based paste wax after each cleaning. Waxing will make cleaning easier and prevent bugs from staining. Please note: Most waxes have a small amount of silicone to improve shine. These are OK! It is the silicone based waxes that should be avoided to prevent problems with painting the aircraft in the future. The user should determine an appropriate schedule to check for damage (i.e., cuts, blisters, perforations, edge lifting, etc.) At the first sign of damage, the mask (boot) should be replaced with a replacement PM Research protective mask (boot).
How do I remove a boot that needs to be replaced?
Carefully score the top surface of the mask with a razor blade knife dissecting the mask (boot) into triangular pie-shaped sections approximately 4″ to 6″ at the base. Pull sections off at approximately a 180 degree angle. If adhesive residue remains after removal of a mask (boot) from a painted surface, clean residue off with a rag saturated with a mixture of 75% MEK (methyl ethyl ketone) and a 25% toluene. Scrape residue off with a platic squeegee. Note: Follow the solvent manufacturer’s safe handling procedures to prevent possible damage to the painted surface. Be sure to check with the the paint manufacturer to make sure that this procedure will not affect the paint you are using in any way. To remove residue from a PLASTIC LENS, DO NOT USE MEK (menthyl ethyl ketone) OR TOLUENE as they may damage the plastic. Use denatured solvent alcohol and some elbow grease.
Do airlines of the Military use these products?
Yes they do. PM Research products have been installed on the aircraft of more than 200 airlines through out the world. We have product installed on jet fighters, cargo planes, helicopters and UAV’s. The same tough material that is used on civil aircraft stays on military planes at Mach speed.
Can i protect prop blades?
Since PM Research cannot control the installation of our products, we do not recommend they be used to protect prop blades. Improper installation might result in an “Out of Balance” situation. Considering the serious consequences which could result, Pexa and PM Research will not assume any risk or liability whatsoever in connection therewith.
What is included with the mask (boot)?
The installation kit includes: an 11 page Shop Manual of instructions including photographs, a clean squirt bottle, a plastic squeegee, a water soluble marking pen and a spout cap for measuring dish washing liquid.
Are additional materials required for installation?
Yes, you will need the following items:
  • 1/4 inch masking tape.
  • Wetting solution consisting of 4 oz. Isopropyl alcohol, 70 percent by volume (common rubbing alcohol) 12 oz. Distilled water 21 drops of clear or white dishwashing liquid, regular strength, or 14 drops of concentrated. We will provide a dropper cap which will fit most US brands of dishwashing liquid.
  • Razor Blade knife (New blade only)
  • Paper towels (High quality, oil free, single ply only)
  • Rubber hospital type gloves
  • Non-silicon based automotive paste wax
For installation over stripes or on a new or freshly polished lens: 600-1500 grit sandpaper, a sanding block, & rubbing compound. Scissors or tin snips. Spray bottle and plastic squeegee are provided.
